GAGE-COCK.

Specification of Letters Patent.

Patented Dec. 13, 1910.

Application led February 7, 1910. Serial No. 542,387.

To all whom it may concer/n:

Be it known that I, CHARLES VRIGIrr, a citizen of the United States,residing at Youngwood, in the county of lVestmoreland and State ofPennsylvania, have invented certain new and useful Improvements inGage-Cocks; and I do declare the following to be a full, clear, andexactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to improvements in ga e cocks.

ne object of the invention is to provide a gage cock having an improvedconstruction and arrangement of valve seat and valve whereby these partsare self adjusting, thus always insuring a perfectly tight tit.

Another object is to provide a valve which will be held in tightengagement with its seat by the pressure of steam or other fluid andhaving means whereby the valve may be held in tight engagement with itsseat when the fluid pressure is removed therefrom.

Vith the foregoing and other objects in view, the invention consists ofcertain novel features of construction, combination and arrangement ofparts as will be more fully described and particularly pointed out inthe appended claims.

In the accompanying drawings, Figure l is a central longitudinal sectionof a gage cock constructed in accordance with the invention; Fig. 2 is across sectional view of the same on the line 2 2 of Fig. 1; Fig. 3 is asimilar view on the line 3*'3 of Fig. 1.

In the embodiment of the invention, as shown in the accompanyingdrawings, 1 denotes the casing of the cock in which .is formed alongitudinally disposed passage 2 extending throughout the entire lengthof the casing, as shown. At a suitable point the casing is enlarged andin said enlargement is formed a threaded passage 3, which is connectedwith the passage 2 and is here shown as being at right angles thereto.Adapted to be screwed into the passage 3 is a discharge nozzle 4l. Theinner end of the casing 1 is slightly tapered and is threaded wherebysaid end may be screwed into the boiler 5 or other device to which thecock is to be attached.

At the inner end of the threaded tapered portion of the casing is formedan annular stop shoulder G, which engages the outer side of the boiler.In the tapered 4inner end of the casing 1 is formed a socket or recess 7in which is arranged a filling or lining 8 formed of fiber. In the fiberfilling or lining 8 is formed a substantially conical valve seat 9 and ashort bore or passage 10, which connects the seat 9 with the passage 2in the casing 1. Formed through the inner portion of the inner end ofthe casing and through the corresponding parts of the tilling S, atdianietrically opposite points, are inlet passages or ports 11 whichopen through the valve seat as shown.

Engaged with the valve seat 9 in the liber filling or lining 8 is asubstantially conical valve 12 formed on the inner end of a valve stem13 which extends entirely through the passage 2 of the casing and isprovided on its outer end with a suitable handle 14. Formed in the valve12 and stem 13 is a passage 15 which terminates in a laterally extendingdischarge opening 16 formed in 011e side of the stem opposite the nozzlelll. lhe end of the passage 15 in the valve is closed by a plug 17, asshown. In the valve 12 is formed a transversely disposed passage 1S,which intersects the passage 15 and which, when the valve is turned inthe proper position, will bring the outer ends of the passage 18 intoalinement with the inlet ports 11. The discharge passage 16 in the stern13 is also arranged in such position that, when the passage 18 isbrought into alineinent with the ports 11, said passage 1G willcommunicate with the nozzle 4. When the valve is turned to bring thepassage 18 out of alinement with the ports 11, the passage 1() will alsobe turned out of alineinent with the nozzle 4t and closed by the wallsof the passage 2.

In the outer end of the casing 1 around the stem 13 is a packing gland19, and on said outer end of the casing is screwed a packing nut 20. Onthe stem 18 and adapted to engage the nut 2O is a stop collar 21 havinga set screw 22, whereby the same is adjustably secured to the stem 13 to`hold the valve 12 into close engagement with its seat when no pressureis applied to the valve from within the boiler. By thusholding the valveinto tight engagement with its seat, any sediment or foreign matter isprevented from gettingv between the valve and seat and thus causing thesame to leak. 1When the boiler is in use, the steam pressure thereinholds the valve into close engagement With its seat, and When thus held,the stop collar is not required.

lt Will be noted that the ports 11 in the inner end of the casing andthe passage 18 in the valve are of less diameter than the passage 15through the stem so that any particles of scale or other matter, whichare small enough to pass through the ports 11 and passage 18 Will bereadily carried off through the 4passage 15 and discharged from thenozzle. It Will also be noted that by arranging the fiber filling asherein shovvn and described, the same Will alvvays be held in place bythe valve and a very small surface or part of the liber is exposed tothe heat or action of the steam or other fluid.

By arranging the valve so that it is held closed by the pressure of thesteam in the boiler when the valve is in closed position, no steamWhatever can escape from the boiler if the cock be broken oif at anypoint outside of the boiler. By reason of this safety feature of thecock, the same is particularly adapted for use on locomotive boilers butcan also be used with beneficial results on any form of boiler.

While I have herein shown and described my improved valve and its fiberseat in connection With a gage cock for boilers, l do not Wish to beunderstood as confining the same to this use, as it is obvious thatthese parts may be used in connection with any kind of cock or faucetfor Water, air, gas or any other fluids.

From the foregoing description taken in connection With the accompanyingdra\v ings, the construction and operation of the invention Will bereadily understood Without requiring a more extended (mplanation.`

Various changes in the form, proportion and the minor details ofconstruction may be resorted to Without departing from the principle orsacrificing any of the advantages of this invention as defined in theappended claims.

Having thus described my invention, what I claim is 1. In a device `ofthe character described, a valve casing having in one end a recess andoppositely disposed inlet ports, a fiber lining arranged in said recess,said lining having ports formed therein to coincide With the ports inthe casing, a conically shaped valve seat formed in said lining andcommunicating with the ports therein, a valve stem operativelymounted insaid casing, a conical valve on said stem adapted to engage said valveseat, said valve and stem having formed therein discharge passages Whichare adapted to be brought into and out of communication With the portsin said casing cessed inner end adapted to be engaged With a boiler,said recessed end having formed therein oppositely disposed inlet ports,a liber lining arranged in the recessed end of said casing, said lininghaving formed therein inlet ports communicating With the ports in saidcasing, a conically shaped valve seat formed in said fiber lining, aconically shaped valve arranged in said seat and adapted to be held intight engagement therewith by the pressure of the fluid in the boiler,said valve having formed therein a transverse passage adapted to bebrought into and out of alinement With the ports in the casing and fiberlining, an operating stem formed on said valve and projecting throughsaid casing, said stem having a passage communicating With the passagein said valve, and a discharge nozzle adapted to com'municate With thepassage in said stem when the valve is in an open position.

3. In a gage cock, a casing having a recessed inner end and a centrallongitudinal bore extending therethrough and communieating with saidrecessed end, a discharge nozzle connected With said casing, a fiberlining arranged in said recessed end, said lining and end having formedtherein oppositely disposed inlet ports, a conical valve seat formed insaid lining, a conical valve engaged With said seat, said valve havingformed therein a transverse passage adapted to communicate With theports in said fiber lining, a stem formed on said valve and projectingthrough the bore in said casing, said stem having a passagecommunicating at its inner end With the transverse passage in said valveand opening at its outer end through the side of the stem, opposite saiddischarge nozzle, said passage having a greater diameter than thetransverse passage in said valve, a packing nut arranged on the outerend of' said casing around the projecting end of said stem, and means onsaid stem to hold the valve in tight engagement With its seat.

4. In a gage cock, a casing having arranged therethrough a centrallydisposed bore, a discharge nozzle communicating With said bore, a liberfilling or lining arranged in the inner end of said casing, a conicalvalve seat formed in said filling, a conicallyshaped valve adapted to beengaged With said seat, said valve filling and casing having formedtherein inlet ports and passages adapted to be brought into and out ofalinement by the turning of the valve in its seat, a stem formed on saidvalve and projecting through the bore in said casing, said stem havingformed therein a discharge Vpassage opening through the end of the valveand communicating at its inner end with the discharge nozzle when thevalve is turned to an open position, a plug to close the inner end ofsaid passage, a packing gland and nut arranged on the outer end of thecasing around said stem, a stop collar arranged on the stem, a set screwadapted to hold said collar in adjusted engagement with the valve stemwhereby the Valve will be held in tight engagement with its seat, and a10 handle on the outer end of said valve stem.

In testimony whereof I have hereunto set my hand in presence of twosubscribing Witnesses.
